More than 37,000 people have signed a Care2 petition requesting that Disney air a public service announcement before its screenings of Finding Dory, premiering on June 17. It's titled "Disney: tell fans to find Dory, not buy her."

The issue is that following the release of Finding Nemo in 2003, clownfish sales rose 40 percent. (Nemo is a clownfish.) The new petition's mission statement continues:

"Fortunately, Clownfish can be bred in captivity, so the market has been partially fulfilled that way. But Blue Tang Fish cannot be bred in captivity, so there is no way to fill a demand in pet Blue Tang except pulling them from their natural habitat. If Disney does not place an explicit warning at the beginning of the film asking viewers not to adopt Blue Tang like Dory, then we will see a sharp decline in their population."

The post also notes that "the transition from ocean to captivity is very hard on reef fish like Clownfishes and Blue Tang fishes, often costing them their lives" and that "researchers are seriously panicking" about the potential Finding Dory effect.
